title: Gastric mucosal prostaglandin synthesis in the presence of Campylobacter pylori in patients with gastric ulcers and non-ulcer dyspepsia.
abstract: It is unclear how Campylobacter pylori (CP) interacts with gastric mucosal prostaglandins (PG). In a double-blind study we measured gastric PG synthesis in 22 patients with benign gastric antral ulcers (GU) and 26 with non-ulcer dyspepsis (NUD). CP status was determined by histology and bacteriology: 26 (16 GU plus 10 NUD) were CP positive, and 22 (6 GU plus 16 NUD) were CP negative. Patients with severe gastritis regardless of CP status) had significantly higher PGE2 and PGI2 values than those with mild gastritis. Severe gastritis was found in 36% of CP-negative subjects and 77% of the CP-positive patients (chi 2 = 8.64, p less than 0.01), but no significant differences in PG values were found between CP-positive or -negative patients.
